I initially started watching this show as part of my train chikan project. I don't remember how I found out about the train scene, but I did and here I am writing a review. OK just to preface: this show is basically comprised of short (4min) scenarios involving Keisuke and one of his sisters (not blood related) engaged in various lewd behaviors. There is a focus on big breasts with each girl having huge watermelon-sized tits, as well as pretty prevalent themes such as public sex, defloration, and facials. Other fetishes also make appearances such as lactation, anal, bdsm,soapy massage, train groping, and then something read more

Maybe its becouse i like romance.

I did not really enjoy this. It had no story, which is fine. no humor at all. half the reason i watch anything is to laugh, and be happy about it.

Once again the incest is only there as a 'tack on' adding little to the paper thin plot. Oppai is the dominate theme to this one, along with a varity of common fetishes. none of it particularly struck me as great.

Reveals? Character development? What's that? ...Well, one of the ladies in Episode 2 turns out to be... nah, you check it out.

The male lead is plain-looking. All of the ladies are voluptuous, some looking more mature and others a bit younger. Each one has a distinctive design, and their own naughty fetish. Each voice fits each character well. Music and SFX is nothing remarkable, neither read more

A guy who lives with 10 hot sister and smashes every single one of they.

Yes thats it, there's not a story to review because the sex scenes just happens by accident of the sisters just tease him in order for it to happen and thats all, there's nothing behind it, but if you just want to beat the meat, well the scenes are short but remind that there's 10 sisters for every taste. That was one of my first hentais, and i thank Ane to Boin to introduce me into this world.

Theres tons of girls for every taste (except for lolis, since i don't remember read more
